Application filed March 13, 1920. Serial No. 365,56t.

To all whom it may concern.

Be it known that I, ERNEST H. DuvAL, a citizen out the United States, residing at Monroe, in the county of Monroe and State of Michigan, haveinvented new and useful the construction or operation of the ma'-.

chine, and whereby a part of the lOOX when brought to engage therewith will have impressed thereon direction, designating, description matters or characters.

A further object is to mount on a box making machine, a printing roller having means whereby the same is held inactive or in non-printing position and also having means for preventingthe same from making more than one impression on a paper board, when the latter is brought to engagement therewith, regardless of the length thereof orthe time required in its travel under the printing roller.

A still further obj ect of the invention is to arrange on one of the shafts of the crimping or scoring device of a paper box machine a feed. roller, on an adjacent shaft an impression roller carrying type, to provide means whereby the inking roll will be brought over the type, and to also provide means whereby the printing roll is normally held immovable regardless of the turning of the shafts, motion being imparted to the said printing roll by the engagement of the paperboard between the same and the feed board, and means being further provided for holding the printing roll after the same h made an impression uponthe paper board until the latter has been. moved from between theimpression and printing rolls, so that only one impression can be made on the board.

It is a still further object of the lnvention to produce a printing or marking attachment for paper box machines in which roll immovable until after the same has been brought to printing or marking posiw t1on,so that only one impression on a single artlcle will be made.

Many other objects and advantages will present themselves as the nature of the in- Figure 1 is a top plan view of the improvement.

Fig. 8 is a longitudinal sectional view through the inking roller.

Fig. 9 is a sectional view approximatel on the line 9-9 of Fig 1.

Fig. 10 is a detail sectional view approximately on the line 10-10 of Fig. 9.

Referringnow to the drawings in detail the numeral 10' designates an Lbeam which is a part of the-frame of the box making machine. Below the Lbeam 10 are superimposed longitudinally arranged shaft-s 11 and 12 that carry the (Jo-engaging score rolls 13-13 and let-J4. respectively. The shafts are revolved by the usual means (not shown) and the paper or board is creased or scored by the rolls 13 and 14..

To the lower flange of the I beam 10 is secured the support of my improvement. The support includes two spaced bars 15 that have their outer ends flanged to form the same withjaws 16 that engage one of the edges of the lower flange of the beam 10. Each of the plates 15 has its upper surface provided with teeth 17 and these teeth are engaged by similar teeth 18 on the movable jaw m m ers 1 9 at the supp she Patented Uct. ii, rear. i

v. blocks comprising the body portions of the movable jaws 19 have elongated slots 20 therethrough, and the plates 15 have upstanding bolts 21 that ;pass through the slots. These'bolts are engaged'by nuts 22 that contact with the outer faces of the block or body members of the movable jaws 19; The jaws 19 engage with the inner edge ings in these lugs and the body of-the bracket Y enten'sion 35. The extension'35 has its outer ment.

of the lower flange of the I beam opposite that engaged by the outer fixed jaw 16.

The plates 15, upon their outer ends have 1 alining openings that receive therethrough a shaft 23. The numeral 24 designates binding elements carried by the plates -and which contact with the shaft 23 to hold the Thesame immovable. c

On the shaft 23 is a bracket 25. bracket 25 has a rounded slitted portion 26, thesame having'an opening therethrough receiving the shaft 23. .The numeral 27 designates a binding element that is designed tocompress the slitted portion of the bracket 'tocause a tight frictional engagement betweenthe sameand the shaft 23, and consequently permit of the angular adj ustmentof the bracket with respect :to the shaft, but

effectively holdingithe said bracket at such adjustment. 3 l Thebrackethas on its rear end two spaced upstanding lugs 28. Passing through open:

are shafts 29. On the upper end ofeach of the shafts 29 there is secured one end of a coil sprin g30. The coil portionsof the'flat springs-30 are wound around the respective shafts 29, as clearly illustrated by the drawings, and the spring 30 isconcealed by a cap or casing 31 that is arranged thereover and is secured to the lugs in any desired or preferred manner. The shafts 29 pass through bearing openings in the said cap or casing 31, and are preferabl-y'provided with enlargements or other means for holding the same'against downward longitudinal move 'On'the' lower end ofeach of the shafts 29 there is keyed or otherwise secured a sheave wheel 32.

Thebracket25 has its endopposite that provided with the lugs 28 depressed to form the same with a reduced lip 33. This lip is lapped by a similar lip '34 formed on one end ofaplate which provides a bracket eX-' tension 35. The lip 34 has an elongated slot or opening S'Ztherethrough, and the lip 33 end widened and its sides preferably formed with lugs or extensions 40. Secured to the id sid f the e i ene n 3 the said lugged corners thereof, preferably by removable means 41, are bearing brackets 42. The brackets 42 have journaled therein a shaft 43. The shaft preferably has its central portion enlarged and threaded at the ends thereof. These threads are engaged by internal threads on cap plates or disks 44. The cap plates or disks clamp on the shaft 43 a wooden roll 45 that has on its peripherya felt facing 46. This provides the inking roll, a quantity of ink being fed to the felt facing 46. On end end of the shaft 43 there is keyed a grooved wheel 47.

On the shaft 12 of the crimping or scoring machine, in a line with the inking roller, is a feed roll. This feed roll is constructed of metal and is of two parts, 48 and 49 respectively. The section 49 has openings 50 directed toward its'end and reduced openings that register with the openings 50. The section 48 has its ends provided with threaded orifices 51' that register with the last mentioned openings in the section 49. Arranged in the openings 50 are headed bolt members 52; the heads of the said bolts are designed tobe engaged by socket Wrenches wherebythe said bolts may be screwed in the threaded orifices 51, and also whereby the sections of the feed roll are connected and bound on the shaft 12.

On the shaft 11, directly opposite the feed roll is the printing or impression roll. This roll also comprises two sections 53 and 54,

connected by bolts 55' in the same manner as are the sections of the feed roll. The sec tions 53 and 54 of the printing roll are, however, in the nature of shelves, which are, of course, semi-cylindrical in cross section so that the sections do not contact with the shaft 11. However, the printing or impression roll has'secured therein. at or adjacent to its ends bearing rings 56. These rings are preferably constructed of bars and contact lightly with the shaft 11. On the outer periphery of the printing roll, and adjacent to the ends thereof, there is secured a pair of split bands 57 respectively. These bands are connected to the printing roll by screws 58, and to the opposite sides of the respective screws 58 are adjusting screws 49. The heads of the screws 58 and 59 are wholly received in the split bands 57 When the split bands 57 are to be held tight on the printing roll the screws 58 are screwed entirely home, and the screws 59, being of a length equaling the thickness of the bands are also screwed home. lVhen the bands are to be adjusted away from the printing roll, the screws 58 arepartly unscrewed, and the screws 59 are screwed homewardly into contacting engagement with the printing roll and inward of the periphery of the bands. Thus the bands may be arranged tightly against the printing roll and to a limited extent be positioned away from the same, and

through the medium of the screws, the said llll bandsare effectively sustained in either of such positions. Thus the bands may be adjusted to engage with different thicknesses of paper to facilitate thefeeding operation thereof. It is to be noted that the combined length of the bands 57 are considerably less than a whole circle so that the confronting ends thereof are spaced a distance away from each other andthe ends of the oppositely disposed bearings of the bands are till sustained in alinement with each other.

The printing or impression-roll has,'adjacent to its ends peripheral grooves. These grooves each include an inner widened passage and an outer reduced passage 61 that centrally communicates with the widened passage. Thus the grooves are T-shaped. The printing orimpression roll has, at desired points openings 62 that are of a size passage 60 of the T-shaped slots. these openings heads of bolts 63 may be passed, and the said bolts move into the "IF-shaped. grooves. The bolts pass through suitable openings in a chase or other device 64 that carries the type 65. The bolts 63' are engaged by small nuts 66.

The type carrying or printing roller is preferably integrally provided at its ends with grooves 67 and 68'respectively. These grooves are continuous and each of'the same has secured therein a flexible element or cable 69, and each of these cables is trained around one of the sheave wheels 32 and secured to the said sheave wheel. The printing or impression roller has at one of its ends a grooved wheel, and this grooved wheel receives therein a twisted belt 71, the said belt being also trained around the grooved wheel 47 of the shaft of the inking roller.

Referring nowparticularly to Fig. 2 the numeral 7 2 designates a pamrboard which may be crimped by the score rollers 13 and 14 and which is designed to have impressed thereon the printing matter carried by the printing orimpression roller. Before proceeding further it should be'fully understood that the feed roller does not contact with the printing roller, and also that the spring 30 through the medium of the flexible elements or cables 69 that connect the same to the ends.

tween the feed and impression rollers, the

same will be engaged by the split bands so that thepaper board 72 will be positively fed between the rollers. r The impression roller will revolve in the di ecti n f the arrow in the said Fig. 2. The turning of the printing roller will also turn the ink roller so that the type on the impression roller will be properly inked. After the type is.

brought to engage with the paper board 72 the printing roller will have turned so that the ends of the split bands thereon will be brought opposite the feed roller as clearly disclosed in 4 of the drawings. As no frictional engagementis exerted between the paper and the impression roller, and also as the spring- 30 exerts tension to return the roller to its initial or normal position, the paper 72 must pass entirely from between the rollers without further influencing the printing or impression roller. After the paper has thus passed the spring will immediately return the printing roll to its normal position.

Of course any number of paper boards or sheets 72 may have printed or other matter impressed thereon, but only one of such impresses may be made on a sheet. Thisin itself is a distinctly novel feature of the in vention. The type or other matter may be readily secured to or removed from the impression roller, so that various classes of such matter may be impressed on the different boxes manufactured. All of the parts of the improvement are extremely simple and are not liable to get out of order. The device maybe readily attached to a crimping or other box making machine without interfering with the operation of the machine or the parts thereof, and it is believed that the foregoing description, when taken in connection with the drawings will fully set forth the construction and advantages of the improvement. While I have described the roll on the shaft 12 as a feed roll the same is really in the nature of a platen as the impression on the sheet to be printed is made thereagainst.

Paving thus described the invention, what I claim is V 1. A. revolving platen, a normally stationary printing rolltherefor, means actuated by means for holding the printing roll against the influence of the sheet after an impression has been made thereon and after the printing surface of the roll has been brought away from the sheet, and means for returning the printing roll to initial position after the printed sheet has been brought from between" the roll and platen.
